Is it certain that Irene von Byzanz is the birth daughter of Empress Zoe? I think there is a mistake here. In fact, it appears that she appears to be the daughter of Pulcheria Sklerina, and thus has over the Skleros lineage through marriage of Romanos scleros with Nal-Taghlibi directly descended from emirs of Mosul, as well as over the maternal ancestral lineage, an exegete of the Koran as well the chiefs and guardians of the Kaaba were. So it was before the entry about the maternal ancestry Irene of Byzantium was changed. The whole pedigree is falsified and I suspect that there is a misunderstanding which has to be resolved.
